Extractions: They say that "necessity is the mother of invention" and after several years of license production of thousands of metal propeller blades for the U.S. military, the end of World War II created the need for new products to replace this business. Robert Hartzell was quick to recognize this need and hired David Biermann, an expert in propeller research at NACA, to lead the company in development of new products following the war. Biermann and his team began one of the most prolific periods in the company’s history. In addition to developing all-metal controllable pitch propellers followed shortly thereafter by constant-speed propellers this team also developed the following industry firsts: The first composite propeller blades Having already been involved in the NASA Advanced General Aviation Transport Experiments (AGATE), in 1997 Hartzell was selected by NASA to serve as the exclusive propeller system partner on the General Aviation Propulsion (GAP) program. Other partners include Teledyne Continental Motors developing a new technology 2-stroke diesel engine, as well as Cirrus Design, Lancair, and Piper supplying test bed airframes. Major objectives of the program are to develop the next generation of technologies that will increase efficiency, safety and performance while reducing noise and cost. Hartzell tested its first prototype in the latter half of 1998. Results from the new, highly swept blades were very promising. Further testing with the new Continental engine is scheduled for 1999, with flight testing to begin in the year 2000.

Extractions: T he 64-year history of the gas turbine industry is a story marked by growth and change. Its products have come to dominate aviation propulsion and, more recently, electrical power generation. Some of these changes were discussed at the February conference, "Gas Turbines for a National Energy Infrastructure", sponsored by ASME's International Gas Turbine Institute and the U.S. Department of Energy in Arlington, Va. The tenor of the talks, however, was in contrast to the industry's history. During the conference, the decade-long upsurge in electric power gas turbine orders—and the more recent downturn—was a dominant topic, and the word "bubble" was used in some discussions to describe it. A bubble, of course, describes something that lacks firmness, solidity, or reality. In its worse sense, it can be applied to a delusive commercial or financial scheme, such as the recent dot-com hysteria.

Extractions: Innovation in the civil aviation market encompasses both the giant Airbus A380 and the tiny Adam Aviation A700 (below). The introduction of gas turbines to generate electricity has been revolutionary in many ways. And while the fuel of choice, clean-burning natural gas, was a relatively stable $2 to $3 per million Btu, everyone was happy. But with demand for gas rising as a consequence (in part) of the number of natural gas-fueled power plants having gone on line in the 1990s, the price spiked to $6 to $8 per million Btu in 2001 and has stayed close to that range every since.

Extractions: Site Map What's New Join/Renew Aviation Classifieds ... Aviation Forums By Steven W. Ells (From AOPA Pilot , August 2000.) P rompted by the promise that leaded aviation fuel will be going the way of the dodo bird and by NASA-funded development of new-technology general aviation engines, no fewer than five companies are currently working on diesel engines for the light aircraft of tomorrow. In addition, two companies have lightweight, fuel-efficient turbine powerplants in development. The diesel engines are not rehashes of the rattling, smoking, gutless diesels that have appeared from time to time in various automobiles over the years. Every one of the new designs is turbocharged. Four of the engines being developed are rated at 200 to 205 horsepower. Two of these engines are being developed overseas; two of the engines are water-cooled, and one is an aircooled radial. And at least three of the engines, the Teledyne Continental Motors CSD-283, the SMA Morane Renault MR 200, and the DeltaHawk V-4, are scheduled to appear at EAA AirVenture 2000 in Oshkosh early this month. Based on reports from the manufacturers, these engines will be capable of lower fuel specific consumption numbers than the most efficient engines of today, will run more smoothly, have much lower engine parts counts, and be capable of longer TBOs than any avgas-fueled engines.

For these reasons, the turbojet and the related turbofan have become the dominantforms of aviation propulsion while the thermojet faded into obscurity.

Extractions: - Donald Shaw Two people are credited with inventing the jet engine . Sir Frank Whittle of Great Britain and Hans von Ohain of Germany both conceived of and built the first jet engines during the 1930s independently of each other. Whittle first originated the idea of the jet engine as a 22 year old officer in the Royal Air Force. He was awarded a patent for his innovation in 1932 and published his findings widely, but his ideas received little attention. Undeterred, Whittle went to work for a research company called Power Jets in 1936 and proceeded to develop a working model of his engine for possible military applications. After tackling and solving many technical problems, Whittle finally began receiving support from the British government in 1939. Sir Frank Whittle and Hans von Ohain Meanwhile, German engineer Hans von Ohain had begun his own independent studies of jet propulsion in the early 1930s while working on his doctorate at Göttingen University. von Ohain had completed a working model of his engine by 1935 and approached Ernst Heinkel about building an aircraft to test such a device. Detailed work to design and build both a more powerful engine and a suitable airframe began in 1937, and von Ohain's engine was the first jet to fly when the Heinkel He 178 took to the air on 27 August 1939.

Extractions: Teledyne Continental Motors Selects Advanced Engine Flight Test Contractor LOS ANGELES - March 16, 2000 - Teledyne Continental Motors (TCM), a business of Teledyne Technologies Incorporated (NYSE: TDY) announced today that it has selected Mod Works, Inc. of Punta Gorda, Florida to assist with the installation and initial flight testing of the NASA sponsored advanced Jet-A fueled general aviation engine. The goal of the NASA General Aviation Propulsion (GAP) Program is to develop and flight demonstrate revolutionary propulsion systems for general aviation aircraft to support revitalization of the U.S. General Aviation Light Aircraft Industry. The TCM GAP engine prototype, which is currently undergoing development testing at the company's Mobile, Alabama facility, is designed to be a compact four-cylinder, 200 horsepower compression ignition engine powered by Jet-A fuel. Jet-A, which is widely available throughout the world, is used by turbine aircraft while low-leaded gasoline fuels are used in most of today's certified light aircraft. The TCM GAP engine design is also testing several enabling technology concepts designed to reduce engine vibration and to provide lower acquisition and operational costs. Program objectives for the GAP engine include a 25 percent fuel efficiency improvement, a 75 percent increase in time between overhaul and a 50 percent reduction in cost as compared to current gasoline powered aircraft engines of similar horsepower. Through the use of an integral monoblock casting, the engine is expected to be comparable in weight to gasoline powered aircraft engines of similar horsepower.

FAX YOUR ORDER Two major technology development programs in the United States, the General Aviation Propulsion (GAP) and Integrated High Performance Turbine Engine Technology (IHPTET) programs, are beginning to demonstrate real advances in turbine engine efficiency and performance. This advancement of gas turbine technology will drive manufacturers to produce new families of engines that offer greater thrust with improved fuel efficiency and lower operational costs. The challenge to incorporate these advances into next-generation engines will likely generate in the related industry segments a new competitive drive to offer enhanced capabilities. Crucial factors that will determine success are careful, preemptive production and competitive strategies that can survive a world market that is less than predictable.

Extractions: and Environmental Compatibility Previous Section Table of Contents Next Section Overview The importance of R&D in this endeavor was noted in a study by the FAA Research, Engineering, and Development Advisory Committee. After identifying several important new technologies, their report said "…the synergy and steady advance associated with all of the above technology areas are creating rapidly succeeding vistas of rich new capabilities. As they combine and specific new applications are developed, we have a critical family of technologies that imply major … opportunities for safety enhancement…" At the same time, technological change can be a two-edged sword. In addition to research to exploit potential avenues to increasing safety, continuing R&D is also necessary to assure that new systems and procedures do not inadvertently introduce new hazards. As a 1996 NASA report noted, "The history of aviation is characterized by periods of major quantum jumps in safety brought about by advances in technology, followed by years of marginal improvements. Today we already can see the new technology that may drive the next quantum leap in safety. The challenge is to ensure that our leap in technology to solve past problems does not induce new problems that pose a greater threat. Our next leap must be a leap based on sound research."

Extractions: Home Update Latest Issue Gallery ... FR 3/97 by Heinrich Hemker Several manufacturers have taken the challenge and are developing new engines for single and twin-engine General Aviation aircraft. Along with European manufacturers, US companies are working on promising projects. Still, while the US partners are getting financial and technical support from a NASA program, most of the European manufacturers are working on their own risk. The Austrian company Bombardier Rotax GmbH is the uncrowned king of the engine manufacturers. The Rotax 912 has become the byword for a light aircraft engine: More than 4500 units of the 912 and 914 have been delivered since 1990. The 914F, a turbocharged version with 115 hp take-off power, was certified in September of last year. Rotax expects a sales volume of 1200 four-cylinder engines for 1997. Following a development time of more than 12 years Zoche's Aero-Diesel is now in the middle of the certification process. Two variants are under development: ZO 01A, a four-cylinder radial (140 hp), and the ZO 02A, an eight-cylinder rated at 300 hp. Michael Zoche's engine concept offers several advantages. The engines are extremely light (123 kg for the 300 hp engine) and use less fuel. Also, the vibration level is very low. The engine control via just one lever is simple and the design gives a high reliability: Carburetor icing, problems with the ignition system or vapor lock are unknown to a diesel engine. Zoche expects that the engine to be certified in 1997.

http://www.airventuremuseum.org/collection/aircraft/Williams V-Jet II.asp

Extractions: The sleek five-place Williams V-Jet II was designed and built to prove the concept of a low-cost, Bonanza-class personal jet for general aviation. The all-composite aircraft was designed around a radically new jet engine-the Williams FJX-2, a compact turbofan delivering 700 lbs of thrust and weighing just 100 pounds. Since the 1950s, Sam Williams' company, Williams International, has been a recognized leader in designing and building small, efficient turbofan jet engines. Early Williams's engines powered military target and surveillance drones. Williams International provided engines for the first cruise missiles and the quality and reliability of those engines helped make modern cruise missiles feasible. In the 1980s, Sam Williams set his sights on the general aviation market. He introduced the FJ44, a two-shaft turbofan rated at 1,900 lbs of static thrust. The FJ44 was so small (two feet in diameter and 40 inches long) and so lightweight (447 lbs) that it wasn't practical to retrofit it into existing airframes. To take full advantage of its size, weight, and efficiency would require a brand new airplane. Designer Burt Rutan was an employee of Beech Aircraft Co. at the time, and he convinced Beech's management to take up Williams' challenge. Beech's proof-of-concept prototype was called "Triumph." It flew in July 1988-the first aircraft to use the FJ44 engine. Though it never entered production, the Beech Triumph demonstrated the performance and economy promised by the FJ44. Another prototype, the Swearingen SJ30, used the FJ44 and first flew in early 1991.
